How Louisville Used GPS to Improve Residents' Asthma

Louisville, Kentucky has some of the worst air pollution in the U.S., which is particularly bad news for the 85,000 people in surrounding Jefferson County (about 11 percent of the population [PDF]) who have been diagnosed with asthma.

The air quality situation in Louisville won’t be changing anytime soon, but a new study with sensor-equipped inhalers shows that technology can help people with asthma cope, as CityLab reports. The two-year AIR Louisville project involved the Louisville government, the Institute for Healthy Air Water and Soil, and a respiratory health startup called Propeller, which makes sensors for inhalers that can track location and measure air pollutants, humidity levels, and temperature.

Propeller's inhaler-mounted sensors allowed the researchers to monitor the relationship between asthma attacks and environmental factors and provided new insight on how air quality can change from neighborhood to neighborhood. The sensors—which are already used by doctors, but have never been deployed citywide before—can measure levels of nitrogen oxide, sulfur, ozone, particulate matter, and pollen in the air, plus track location, temperature, and humidity, all of which can impact the risk of asthma attacks. The sensors send Propeller data on when, where, and how many "puffs" patients take to track how often people are resorting to emergency medication.

Propeller sent out app notifications to warn the Louisville program participants of greater risk of an asthma attack on bad air quality days, and showed them where and when the most asthma attacks happened around the city.

The Propeller program illuminated just how much more asthma-triggering pollution the city’s west side (predominantly home to poor, African-American residents) faces compared to other neighborhoods. The data also showed that ozone provoked an uptick in asthma attacks throughout the city, namely along highways. The study may end up influencing air quality regulations, since the researchers found that air pollutants became problematic for asthma sufferers even under the legal levels.

The program had huge short-term benefits, too, beyond collecting research for city policies. By the time it ended in late June, the study clearly had a significant impact on the nearly 1200 people with asthma and chronic obstructive pulmonary disease (COPD) who took part. The asthma group showed a decline in average inhaler use after a year. There was an 82 percent decline in people's weekly average uses of rescue inhalers at the 12-month follow-up, and the participants had twice the number of symptom-free days. The majority of participants said they understand their asthma "very well" or "well," can better control it, and feel confident about avoiding a bad asthma attack.

Now that the program is over, the institutions involved are still working to launch new policies based on the results, like creating citywide asthma alerts and planting more trees.

Jeff Bezos Is Helping to Build a Clock Meant to Keep Time for 10,000 Years

Few human inventions are meant to last hundreds of years, much less thousands. But the 10,000 Year Clock is designed to keep accurate time for millennia. First proposed in 1989, the long-lasting timepiece is finally being installed inside a mountain in western Texas, according to CNET.

The organization building the clock, the Long Now Foundation, wanted to create a tribute to thinking about the future. Founded by computer scientist Danny Hillis and Whole Earth Catalog publisher Stewart Brand, the group boasts famous members like musician Brian Eno and numerous Silicon Valley heavyweights. Amazon founder Jeff Bezos is putting up the $42 million necessary to complete the project, writing that “it's a special Clock, designed to be a symbol, an icon for long-term thinking."

Measuring 500 feet tall when it's completed, the clock will run on thermal power and synchronize each day at solar noon. Every day, a “chime generator” will come up with a different sequence of rings, never repeating a sequence day to day. On specific anniversaries—one year, 10 years, 100 years, 1000 years, 10,000 years—it will animate a mechanical system within one of five rooms carved into the mountain. On the first anniversary, for instance, the clock will animate an orrery, a model of the solar system. Since they don’t expect to be alive for many of the future anniversaries, the clock’s creators won't determine animations for 100, 1000, or 10,000 years—that'll be left up to future generations. (To give you an idea of just how far away 10,000 years is, in 8000 B.C.E., humans had just started to domesticate cows for the first time.)

Though you can sign up to be notified when the clock is finished, it won’t be easy to see it up close. The nearest airport is several hours’ drive away, and the mountain is 2000 feet above the valley floor. So you may have to be content with seeing it virtually in the video below.

Barbie Is Now Giving Coding Lessons

Mattel wants to help 10 million kids learn to code by 2020, and the toy giant is enlisting one of its most career-focused assets: Barbie. According to Engadget, Mattel is working with the coding education company Tynker to make seven Barbie-themed computer programming lessons.

Barbie has been a pilot, an architect, the president, and a computer engineer, so there may be no better character to teach kids the joys of coding. The lessons, arriving in summer 2018, will be designed for youngsters in kindergarten and up, and will teach Barbie-lovers more than just how to make apps. They’ll use Barbie’s many careers—which also included veterinarian, robotics engineer, and astronaut—as a way to guide kids through programming concepts.

There are plenty of new initiatives that aim to teach kids how to code, from a Fisher-Price caterpillar toy to online games featuring Rey from Star Wars. This is the third partnership between Mattel and Tynker, who have already produced programming lessons using Hot Wheels and Monster High.

Kindergarten may seem a little soon to set kids on a career path as a computer programmer, but coding has been called “the most important job skill of the future,” and you don’t need to work for Google or Facebook to make learning it worthwhile. Coding can give you a leg up in applying for jobs in healthcare, finance, and other careers outside of Silicon Valley. More importantly for kids, coding games are fun. Who wouldn’t want to play Robotics Engineer Barbie?
